1)Description of Stragith bevel Gear
Bevel gears are always mounted on shafts that are 90° degrees apart.
Bevel gearss are gears where the axes of the two shafts intersect and the tooth-bearing faces of the gears
themselves are conically sahped.
2) Applications of straight bevel gear
Electric tools, machine tools, cone crusher, printing presses.
3) Features of straight bevel gear
a) Straight bevel gear can provides reduction ratios up to approx 1:5
b) Straight bevel gear is easy to manufacture.
4) Important conecpts of bevel gear
Two important concepts in gearing are pitch surface and pitch angle.
